VtrSendCommandToRunner sends ^L

[jyurek]

The workaround is to set let g:VtrClearBeforeSend = 0.

VtrSendCommandToRunner will try to clear the terminal before running a command with ^L. If your terminal doesn't like that for whatever reason, it won't get cleared and the command won't run because there's a ^L on the front of it. I don't know why, but mine exhibits this behavior.

I'm interested in understanding why ^L doesn't work for your terminal, but an alternate fix for you would be to find a sequence that does work and set it to g:VtrClearSequence, e.g.

let g:VtrClearSequence = "��clear"

	*VtrClearSequence*
	3.11 g:VtrClearSequence~
	The character sequence to send to clear the runner. This sequence is used in
	the explicit VTR comamnd |VtrClearRunner|. In addition, the sequence may be
	used with the commands |VtrSendCommandToRunner|, |VtrResizeRunner|,
	|VtrReattachRunner|, and |VtrReorientRunner| depending on the current value of
	their respective "ClearOn" settings.
	The default sequence will clear any unfinished commands sent to the shell
	prompt within the runner pane and clear the scrollback history to present a
	clean prompt ready for the next command. The character literals, �, for
	<Ctrl-u> and <Ctrl-l> respectively, can be inserted using <Ctrl-v> while in
	insert mode. See the help file, ':help i_Ctrl-v', for more detail.
	let g:VtrClearSequence = "��"
	Default: "�"

I'm having this problem as well. Not sure what the setup issue is. I'm using iTerm if that helps. My fix was to set the clear sequence variable to this.

let g:VtrClearSequence = "clear\r"

I realized the mapping is useless, and removed it. But I probably wouldn't have known the cause without this issue.

I have this issue as well. I am using st as my terminal.
